- rvEllis. invention relatesto a grjaindoor4 `for Va b'oX car,l andlias for one, of itsobjects to provide ya door of this character veinbonlyng lower, upperand intermediate sections which 5 shall be mounted for independent horizontal movement into opened or closed position, Awhich Vshall be providedy at their adjacent horizontal vedges with f means adapted Awhen thesections are in closed position toprevent therebetween of grain, and which shall'embody a construction adapted torporinit tliemto be niade of comparatively light sheet Inetaland yet be of su'ce-nt strength as vto prevent them from being distorted.Z

The invention ,has ior a further object to provide means for slidably supporting vlthe door sections which shall embody horizontal Vtracks secured t'o thec'ar and of triangular formation in ,cross (section,` andslides simii') lar in crosssection to and mounted Within the tracks and having the. door sections secured thereto. r

a horizontal flange- 14a secured, as at 20, to the floor 1 ofthe car. The upper end ofthe standard or studding 14 is'of angular lformation, overlies the vflange 11' of the plate 7, and is secured, asfat21, to the side 2 of the y -Horizontal tracks 22iofsubstantial triangular formation in cross section extend trom the door post 5 to the inner or closed end, of the housing 8, and the greater portions thereof are located wholly within the housing. The tracks 22 are secured, as at 23, to the door post 5, and as at 24, to the standard or stud- `ding 12.V The tracks 22 are spaced from the plate 7', and the open sides 22a thereofV face l `the plate. VThe inner end Yportions ofthe upfper and lower sides-2257er the tracks'22 are cut away, as at 25, for the purpose to be presentlyset forth. Slides 26 which aresim- V-ila'r incross sectionto the tracks 22 are mounted 1n the tracks for endwise movement I with respect thereto. f -K Thedoor comprises a lowersection 27, an 'upper section 28-and anintermediate section 29 which are equal in length and -which are Vgreater in length than the width of the door opening 4; Thedoor section 27 is of greater Ysmooth marginal portions. j VvThe door section 27 rests at its: upon the floor 1 of the car',the door section 29 height than thefdoorsection 29, and the door section 29 is of greaterheightthan the door section 28. lThe door section 27 is securedto four of the slides 26, the door section 28 is selower edge is provided `at its lower edge with an inwardly otset and downwardly extending flange 33 contacting with'the upper edge por tion of the door section 27 and the door section 28 is provided at its lower edge with an' inwardly oiset and downwardly extending flange 84 contacting with the upper edge p0rtion ofV the door section 29, to prevent the grain from escaping from the car when the door sections are in closed position.

The door sections 27, 28 and 29 are located between the plate 7 and tracks 22, and are A greater in length than the plate. Vhen the Vthe inner and outer edge portions of the door sections 27 28 and 29 and the outerend portions of the tracks 22 to elect the closure of the outer end of the housing 8, when the door sections are in opened or closed position. rlhe flap 35 is equal in height to the housing 8 and comprises sections 85a, 35Zfand .350 which are hinged, as at to the standard or studding 14. The flap sections 35a, 35?) and 35e are similar in height to the'door sections 27 29 and 28, and the free vertical edges of the flapsections contacty with the inner end portions 'of the door sections when the latter are in closed position and contact with the onterie'nd portions of the door sections when the latter are in opened position.

Coil springs 38 secured to the standard or studding 14and to the flap sections 35a, 356 and 350 yieldingly maintain the free edges of the lap sections in contact with the door sections 27 28 and 29. The flap sections 35a, 356 and .85C are also employed for the purpose of latching the door sections 27,28 and 29 in opened or closed position, and to permit this to be done the flap sections are provided at their free edges with lugs or ears 39, and the V:door sections are provided near their inner 'edge portions with pins `41. W'hen the 'door sections I27, 28 and 29vare in closed position the ears 39 ofthe flap sections 35a, 3521 and 350 engage the pins 40,'as shown'in Figure 2, and when` the` door sections are in opened position the ears engage the pins 41, Vas shown in Figure 4, the ears being held in engagement with the pins byl thev springs 38. The door sections 27 28 fand 29 Vare provided near their outer ends Vwith handles 'to permit them to f be conveniently moved into closed or opened position, and when it is desired to move the door sections Ainto either ofthese positions,

-it is only necessary to swingv the liap sections 85h and 350 in a direction to carry the 44 which is located at the inner side of the plate? and which yis mounted in guides 44o seciilred to the plate. Thefdo'or section 27 is provided near its loWer edge Withan openvents the grain from Vinterfering With the The filler .36 extends froni'the door post 5 --inivardly beyond theouter end of the plate 7, and extendsf'ioin the 2 of thecar .to the inner edgesof the tracks 2Q. Theiiapseotion Sis provided at its lower 'endvvithahorizont'al flange 35d, andthe lflap Vsection 350 is provided at its upper end with Va horizontal flange 35e which eXtendsthereffro-ni lin the vdirection of the door sections '27 Yand 28, respectively, and which cooperatewvith these. ydoor sections to assist-theelap'fsections in closing the open or 'outerjen'd ofthevhousing at the inner side ofY the door' sections'. The

flap sections 35o and 350 Vare provided with, notches 35i and 35g Jfor the reception ofthe f door-section flanges 33t-and 34, respectively It any grain'should become llodgedin the tracks it will be discharged.throughthe openings 25 of the inner ends Vof the tracks 4f2.2 by the slides 2o during tlie'mo'vement of the ,door sections 27,28- and29rinto opened posit-ion.

To permit the removal from the housing -v 8 of any foreign material that inay enter the lsaine, the plate 7 is provided near its lower l inner corner With a clean-out opening 43 which is closed by a vertical sliding door ing 45 which is closed by a horizontally slidf ing door 46 mounted in guides 47 secured to the outer side ofthe door section.` 'hhe door 4S is provided with a handle l48Whichl extends through 'slots 49Min `the inner and lower sides of thatslide ZicXtendingA across the opening 45.- The handle 48does not pro'- ject outwardlybeyond this slide 26, and in vievv thereof it yWill not interferewith Athe movement of the door section 27v into closed f or opened position. The door 46 is opened to permit thegrain adjacent the door sec-` tions 27, 28 and 29 to How through the opening 45 of the door section 27 and thusrelieve the pressure of the grain against the door sections and enable thein to be readily moved into opened position. The door post 6 is provided With keepersy or rests 50 which are similar in cross sectional formation to the tracks 22 and which receive the outer ends of the slide 26 when the door sections 27, 28

and 29 are in opened position, the keepers or rests 50 being secured, as at51,'to the door post.
